Aniston said she doesn’t wash her hair every day because of the drying effects of commercial shampoo.

“Silicone is a culprit in most shampoos,” said Jennifer. “Over time, it builds up and turns into a hard coating and it cracks and breaks and snaps your hair … I’d say I go every two to three days easily without washing my hair.”

At 46, Aniston looks and feels fantastic in every way, thanks to her longtime dedication to health and fitness. Aniston credits a low-carb diet and yoga workouts for her banging bikini body, Examiner reported.

Unlike other celebrities, Jennifer enjoys aging, saying this is the best time of her life. “I’ve had more fun post-40 than I can remember,” she said. “From a work point of view, a physical point of view, a psycho-therapeutic point of view.”

Aniston has practiced yoga for more than 20 years with Mandy Ingber, her longtime friend and yoga teacher, saying the meditative practice tones her body and calms her mind. “If yoga didn’t exist, I’d invent it,” said Jennifer.

“The closest I’ll ever go is a Derma roller,” said Aniston. “Google it — it’s great. It’s like a little wheel that has little pins, like acupuncture needles in a way, and you roll it and it stimulates your collagen and it also allows for your products to seep into your skin.”

Thanks to her lifetime dedication to health and fitness, Jennifer looks and feels incredible, and doesn’t dread getting older. “I really try not to focus on it too much,” said Aniston. “Society focuses on it way more than we need to.”
